Matthew 12:50

For whosoever shall do the will of my Father which is in heaven, the same is my brother, and sister, and mother.

Ver. 50. For whosoever shall do the will] Lo, here is the right way of becoming akin to Christ; and can we better prefer ourselves? It was an honour to Mark, that he was Barnabas's sister's son. David dare not in modesty think of being son-in-law to a king. Elymas the sorcerer affected to be held allied to Christ, and therefore styled himself Barjesus: as Darius, in his proud embassy to Alexander, called himself king of kings, and cousin to the gods. But the right way to be ennobled indeed, and inrighted to Christ and his kingdom, is, to believe in his name, and obey his will. This, this is to become Christ's brother, and sister, and mother. Sister is named, to show that no sex is excluded. And mother last mentioned, that the prerogative of the flesh may be set aside and disacknowledged.
